Read full descriptionHide full description
SLAB is a voice-first workout tracker and food logger, built for lifters who hate fumbling with their phone mid-set and calorie counters who don't want the friction. Speak naturally. Say "225 for 5, felt heavy" or "200 grams of chicken breast" and SLAB logs it. No tiny buttons. No number pickers. No friction. HOW IT WORKS - Talk to SLAB like a training partner - It parses your voice into structured data - It tracks your calories, workouts, goals, PBs and previous weights, times, and durations - One tap to talk, then back to lifting BUILT FOR THE GYM Your hands are chalked. You're wearing wrist wraps. You're between sets and your rest timer is running. You don't want to tap through forms and scroll number pickers. SLAB lets you log with your voice and get back to work. TRACKS WHAT MATTERS SLAB remembers your personal bests and what you lifted last time. See your progress without digging through spreadsheets. ZERO FLUFF Dark mode only. No gamification. No confetti. No cartoon mascots. Just your lifts, your stats, your progress. SLAB Pro unlocks unlimited voice logging and full training history.

BarbellBeat

There's one question I kept coming back to during my workouts. Why does everyone rest for the same amount of time? Some people recover fully in 60 seconds. For others, their heart rate is still elevated after 90. Yet most training still runs on a fixed timer. So I made this. BarbellBeat uses your Apple Watch to track how your heart rate recovers between sets, and tells you when you're ready for the next one. - Real-time heart rate recovery tracking - Haptic alert the moment you've recovered - Every workout and rest interval saved automatically Train by recovery, not by the timer.

Verdict
The clearest difference is in-app purchases: BarbellBeat at none against SLAB's 2. BarbellBeat also leads on update cadence (every 5 days vs fortnightly). SLAB's advantage is iOS requirement (15.1 vs 17.6). On price, ads and device support there is nothing between them.
